To directly probe the top Yukawa coupling beyond the EW scale, we need to derive the top-Higgs form factors, which describe the momentum-dependence of the top Yukawa coupling [1]}, [2]}, [3]}, [4]}. We present in Fig. REF  the top Yukawa form factor in our two benchmarks, compared to the SM Yukawa form factor. These deviations are especially useful when the off-shellness of the top is comparable to \(\Lambda _y\)  and a large reduction with respect to the on-shell value is observed. These effects could be seen in the tails of momentum distributions. In processes such as \(t\bar{t}h\)  production, where the top quark is probed in time-like momentum and thus the resonant pole structure is probed, this could lead to significant increases in the total cross section  [4]} and especially in differential momentum distributions. However a more quantitative statement for the model requires a dedicated analysis which is outside the scope of this work.
